• After four weeks of work in the Antarctica, Dr Raúl Cordero and Dr Alessandro Damiani, both researchers at the Department of Physics of Universidad de Santiago de Chile, were able to confirm that the extension of the hole in the ozone layer over the Antarctica reached more than 10 million km² in December 2015, i.e. more than twice the average of that period in the past three decades.

​

The measurements were carried out during a campaign in the Antarctic Circle in the context of the Antarctic Scientific Expedition of the Chilean Antarctic Institute (Inach, in Spanish). Dr Raúl Cordero and Dr Alessandro Damiani, both professors at Universidad de Santiago de Chile, were part of the expedition.

The ozone measurement campaign at the Antarctica started on November 15^th and it continued until mid-December. Four researchers at Universidad de Santiago travelled to the heart of the White Continent, where about 600 kg of the best radiometric equipment available were sent.

The expedition was supported by Inach, what allowed the researchers to work at “Unión Glacier” Joint Polar Research Station located at 79 degrees South latitude, at about 1000 from the South Pole.

Constant monitoring

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer starts in the short term, as a result of the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

According to Dr Cordero, “the ozone layer depletion is mainly caused by the presence of ‘ozone destroying” chemicals in the polar stratosphere. These substances are generated by the industrial activity in mid-latitudes.”

Although these substances are everywhere in the planet, high latitudes are the most impacted areas by the layer depletion or destruction, particularly the Antarctica. During the southern spring, this area is affected by a massive destruction of the stratospheric ozone as a result of the particular weather conditions there.

According to the researcher, the ozone depletion process between September and December is favored by the low temperatures in the Antarctic stratosphere and by the Antarctic polar vortex that prevents the ozone from other latitudes from closing the hole.

“When temperatures increase at the end of spring, the ozone massive depletion stops and the weakening of the polar vortex allows the ozone from other latitudes to close the hole. The bad records this year are probably the result of unusually low stratospheric temperatures during last spring,” Dr Cordero said.

Recovery of the ozone layer

In spite of the negative results of this year, Dr Cordero expects that a process to recover the ozone layer continues until the middle of this century due to the actions taken worldwide to reduce the emissions of polluting gases. However, the information gathered highlights the need of adopting mitigation policies and conducting a constant monitoring of the area.

It is also worth to mention that this study included comparisons with databases of other months. According to this, the hole in the ozone layer reached 28 million km² in October, the fourth highest record since the satellite data is available. 

Dr Cordero also highlights the relation between ozone depletion and climate change. “The changes in the hole in the ozone layer could affect the energy balance of the Antarctica. Ozone depletion or exhaustion has affected the temperature of the stratosphere and it correlates with wind and surface temperature variations detected in the Antarctica in the past decades. Therefore, a better understanding of the relation between climate change and the hole in the ozone layer is required. This is the ultimate goal of our work,” he concluded.

• Dr. Renato Chávez and biochemists Luis Figueroa and Javiera Norambuena were honored at the 5^th Congress of European Microbiologists, in Leipzig (Germany) for their research on bioactive compounds from Antarctic marine sponges, which present a high microbial, antitumor and antioxidant activity.

The study’s innovation and impact and the results shown were the reasons for giving the Best Poster Presentation Award to the study conducted by a team of researchers from Universidad de Santiago and Universidad de Chile in one of the most important events worldwide in the field of Microbiology: the Federation of European Microbiological Societies Congress, FEMS 2013.

The research team is composed of Dr. Renato Chávez, researcher from the Faculty of Chemistry and Biology, Universidad de Santiago, and the biochemists Luis Figueroa and Javiera Norambuena, also from Universidad de Santiago, together with other specialists from Universidad de Chile. They conducted the study for three years.

The study is based on the analysis of new bioactive compounds, present in filamentous fungi of Antarctic marine sponges. These compounds show a high microbial, antitumor and antioxidant activity.

Discovering these new species and their properties, supported by the required laboratory research, could lead to potential applications in Biotechnology, especially in the field of Pharmacology.

Regarding the study’s development, biochemist Javiera Norambuena says that, in order to find these bioactive compounds, it was necessary to search poorly explored places, as in those places there are more possibilities of finding non-cultured organisms. “That is the reason why we isolated fungi from Antarctic marine sponges, which usually have chemical compounds containing secondary metabolites; that is to say, they are not required for the organism’s survival, but they give it advantages over other members of the population”, she adds.

Regarding the study’s results, biochemist Luis Figueroa notes, “a high percentage of the isolated fungi could not be identified, which suggested the existence of new genera in the microbial community from Antarctic marine sponges; therefore, we can conclude that the fungi community in the Antarctic marine sponges studied is completely different from the one in common marine sponges.”

“We are on the right track”

Dr. Renato Chávez, researcher and professor of Faculty of Chemistry and Biology, says, “The honor awarded confirms that our work with fungi from Antarctic sponges is of international interest.”

“The award confirms that regarding the study of Antarctic marine eukaryotes (fungi and yeasts), we are on the right track, what encourages us to continue in this line. We are aware that we are dealing with new species that have not been described yet, so describing them is among our next goals. Also, we know that these species produce chemicals with very interesting properties that could be used in the Biotechnology field. As for the students participating, this award is most certainly an incentive for them as young researchers,” Dr. Chávez adds.

The full research team that took part in the poster presentation is made up by undergraduate and graduate students from Faculty of Sciences, Universidad de Chile: Marlene Henríquez, Ivanna Araya, Andrea Beiza and Karen Vergara, while the work presented at the Congress is supported by Fondecyt Project 11090192, conducted by Dr. Inmaculada Vaca, from Universidad de Chile.

• Dr. Gonzalo Acuña was elected president of the Chilean representation at the Computational Intelligence Society, which is part of the world’s largest professional and technical association in this field. Also, professor Acuña became Chile’s representative at the Latin American Computational Intelligence Society.

An academic of Universidad de Santiago’s Department of Informatics Engineering, Dr. Gonzalo Acuña Leiva, will preside for two years the Computational Intelligence Society (CIS) Chile Chapter, which is part of the Institute of Electrical and Electronics Engineers (IEEE), the world’s largest professional and technical association dedicated to advancing technological innovation and excellence for the benefit of humanity.

Dr. Acuña was elected president of the Chilean representation of the IEEE-CIS, one of the world´s most renowned and traditional organizations, as it was the first organization founded in this field after the American chapters of computational intelligence and is made up of, at least, sixty academic members from different universities.

“Computational Intelligence relates to the ability developed by computers, for example, to imitate nature or biological processes,” Dr. Acuña says, pointing out that this field includes neural networks and genetic algorithms inspired by biological processes or the animal world, like the ants’ methods to solve problems or the flight of birds.

Although the IC concept seems to be related to Informatics, Dr. Acuña says that it has to do with dynamical systems and mathematical models and not necessarily with programming.

Computational Intelligence is not Artificial Intelligence

Dr. Acuña says that the concept of Computational Intelligence should not be taken for Artificial Intelligence, as the former refers to “mathematically modeled ideas that help to solve optimization problems and other engineering works. It refers to mathematical tools that are commonly used by computer programmers to solve different problems, as they can be applied to all imaginable fields.”

Dr. Acuña has been working in this field for several years and he has specialized in the study of neural networks, interconnection systems inspired by the animal nervous system functioning and SVM (Support Vector Machines), a group of supervised learning algorithms that can be applied to different areas.

At present, the academic is leading a Fondef project where he is applying this knowledge to mining industry.

“With this Computational Intelligence tools we are building predictive models for the availability of physical assets in mining industry, like shovels, large trucks or the enormous equipment required for mining operations that involve high maintenance costs. Therefore, if we are able to anticipate the equipment availability, mining industry can improve preventive maintenance and reduce costs,” Dr. Acuña explains.

Youngsters and Latin America

About his recent nomination as president of the IEEE-CIS Chile Chapter, Dr. Acuña says that the efforts are oriented to promote the Chapter and to motivate young people through CI Summer Schools, which are “the ideal opportunity for students preparing their dissertation work to participate, as leading figures in this field give presentations and many of our members offer tutorial sessions. It is the occasion when we meet as a community.”

Finally, there is also news about this field at a regional level, as two weeks ago, in a congress held at Bariloche, the Latin American Computational Intelligence Society was founded, where Dr. Acuña and an investigator from Universidad de la Frontera were appointed national representatives.

• Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago de Chile, presented a novel initiative for the academic field at the International Educational Summit 2016: XII Conference on Higher Education Management.

Claudia Matus and Bárbara Ossandón, both professors at the Physics and Mathematics Teaching program of Universidad de Santiago, had a remarkable participation at the International Educational Summit 2016: XII Conference on Higher Education Management.

This activity has become one of the most important meetings for exchanging experiences at a management level among higher education institutions in Latin America, with the participation of renowned international experts.

The conference was held at the Casa Central of Pontificia Universidad Católica de Chile and professors Matus and Ossandón presented their work “Comunidad Práctica de Aprendizaje como elemento clave de gestión en el rediseño curricular de una carrera de pedagogía.”

“We designed a new innovative curriculum that based its pedagogical principles on a spiral modular design that involves the integration of theory and practice and is focused on the classroom activity and the student,” professor Ossandón explained.

She highlighted “the need of understanding curriculum management through an interdisciplinary team work and professional management. This means to strengthen the role of the head of the program and
distribute his/her tasks in four coordinations: practice, teaching, laboratories, and outreach and engagement. This last coordination has the purpose of providing feedback on the curriculum.”

“This interdisciplinary learning community that works collaboratively is made up of physics and mathematics teachers focused on didactics; an anthropologist, and other professionals,” she said. It is a group of committed people working in an environment where interdisciplinary collaborative work is usually understood as the sum of individual works,” she said.

“The strength of this initiative is the new design of the curriculum of the Physics and Mathematics Teaching program that allowed us to be accredited for seven years,” she added.

Conclusions

“What we want to share is the idea that, to achieve curriculum innovation, the line-up of collaborative interdisciplinary work teamsis very important in order to make the program management a profesional activity, as well as to encourage constant self-evaluation, what will result in constant improvement,” Professor Ossandón said.

The conference “helped us to validate the pedagogical principles of our program according to the different presentations given that addressed the latest trends in education that, in turn, allowed us to validate our own community, our team made up of the four coordinations. Besides, it enriched even more our pedagogical learning proposal,” she said.

“This activity is also an example of learning practice community,because on this occasion we learned about an education research network. This network is formed by universities in four continents and

it was created by the initiative of different communities, as the most advanced way of distributed leadership in the knowledge society, as Hargreaves said. This conference is a learning practice community
itself,” she added.

“We propose a professional, pro-active approach, where the head of the program can conduct research works with collaborative teams in the medium and long term,” she concluded.

• Professors Dr. Juan Sepúlveda, Dr. Astrid Oddershede and Dr. Felisa Córdova, who were invited by the International Academic Program, took part in a seminar where they acquired new tools for problem solving through creative thinking. This will considerably benefit the students and will allow improving and updating the Industrial Engineering curricula.

Between January 07th and January 09th, the academics of our University’s Department of Industrial Engineering, Dr. Juan Sepúlveda, Dr. Astrid Oddershede and Dr. Felisa Córdova were invited by the International Academic Program (IAP) to take part in the workshop “Design Thinking and Innovation” at the renowned Harvard University, USA, where they acquired tools to solve problems in an innovating and creative way. They said this will enrich the educational experience of their students.

Specifically, the seminar was given by Professor Srikant Datar to 22 academics from different Latin American universities selected by the IAP and it was held at the Innovation Laboratory of Harvard Business School

Dr. Juan Sepúlveda, the Head of our University’s Department of Industrial Engineering, claimed that this continuing education program for university teachers “is a great progress in updating our teaching methodologies and in adopting thinking and problem solving innovative techniques that we will implement in our classrooms starting this year.”

“The topic that gathered us together in this seminar- Dr. Sepúlveda explained- was ‘Design Thinking’, an approach to develop innovation that is based on the designers and architects’ point of view, which have a very different way of thinking from engineers.”

Dr. Sepúlveda added that Design Thinking is “a very useful methodology to leave behind the conventional paradigms of engineering management, and for us academics, it will be very helpful to show our students that creativity can contribute to solve a large number of problems of our professional lives.”

“After this academic experience, we look for transmitting what we learned to students, so that they dare to break the known models and seek for creative answers to the challenges that they will face in the field of management,” he pointed out.

While, Dr. Felisa Córdova agreed with Dr. Sepúlveda and said that in this visit to Harvard, “we were able to see the learning and teaching methodologies used at this renowned American university and also had access to the researches that professors are now conducting there.”

“After this seminar, the idea is to promote and develop a disruptive way of thinking among our students at Universidad de Santiago de Chile and encourage them to develop a creative thinking, so that they behave out of the ordinary, break the paradigms to implement their innovations then,” Dr Córdova said.

“In the end, this will have an impact on our students, because when they know that their professors are constantly updating their knowledge and that they are taking part in academic activities at Harvard University, for example, they feel supported by teachers of excellence, what in turn makes them more committed with their classes,” she stressed.

For his part, the Head of the Department, Dr. Sepúlveda, concluded that updating knowledge and acquiring new learning and teaching experiences that are world-wide recognized “give our institution a great boost to keep our strong commitment to continue forming world-class professionals.”

• Dr. Edmundo Leiva, professor at the Informatics Department of Universidad de Santiago and Jorge Segura, who is pursuing a Master´s Degree in this area, developed a software program that recognizes facial microexpressions that evidence basic emotions more effectively than the human eye does. The program can detect sadness, anger and rage - that are expressed through involuntary expressions - even when they last for less than a second. According to professor Leiva, it could have multiple applications: detecting criminals at airports, selecting and recruiting staff for key positions or helping in psychological virtual therapy on Internet.

Affective computing is a research field that relates to the interpretation of human emotions through technology. It looks like science fiction, but it is more real than it appears, and our University is making progress in this matter.

Dr. Edmundo Leiva, professor at the Department of Informatics Engineering of Universidad de Santiago, together with Jorge Segura, a student at the Master’s Program of that unit, developed a software program that can identify emotions by reading human facial expressions even when someone is trying to hide them.

By means of a camera that captures facial muscles movements, it is possible to identify microexpressions, even those lasting less than a second.

“When a person is trying to deceive someone, this program recognizes his/her facial microexpressions. Microexpressions are brief facial expressions shown according to the basic emotions experienced, like anger, happiness, sadness and disgust,” professor Leiva explained.

Professor Leiva - PhD in Informatics - said that although there are experts who study and get certified in interpreting emotions through the face, their estimation range is only 63%, while “our software program has exceeded 70%.”

“Very few people are able to detect microexpressions, because an evident anger expression could hide or mask sadness, what could show for half a second. This microexpressions detector can read that emotion in a fraction of a second,” he explained.

Professor Leiva explained that this innovative tool has a wide scope of applications, from supporting police work to detecting the truthfulness of data provided in recruitment and selection processes of staff for key positions.

“It could be useful for detecting terrorists at airports, or even for virtual therapy given by some psychologists through Internet and Skype. The therapist could have some indications if the patient is lying or, for example, in case of senior people, if they took their medication or not,” professor Leiva said, betting that the list of possibilities could be very long. He also thinks that in the future, it could become an application for mobile devices.

“We speculate that in the future, even Google Glasses (optical displays connected to Internet networks) could have a microexpression recognition device, so that everyone would be able to detect if a person is trying to hide an underlying emotion,” he stressed.

The psychology field that related to facial expression metrics was developed by the American psychologist Paul Ekman, who is a pioneer in detecting the facial expressions of seven basic emotions considered to be linked to the atavistic part of the brain. “Sadness, anger, happiness, fear, surprise, contempt and disgust, which are emotions that all human beings show as a species heritage and not as a trait of a particular culture,” professor Leiva concluded.

The Department of Informatics Engineering is planning to show its work in this line and other research lines to the University community through different stands displaying related technology. Professor Leiva will participate to show this interesting program to anyone who is interested in knowing better about this matter.

• Dr Paola Arias, together with her research team, will search for signals of new particles in cosmological observations and lab experiments, in the context of a Fondecyt Regular project 2016. Currently, there are independent efforts worldwide oriented to this search; the team’s goal is to propose new and better detection techniques.

The search for new particles has been in the general interest for a long time. The most popular example in this field of study is the Large Hadron Collider (LHC), the world’s largest particle collider that allows studying the elements which are part of the matter that forms the Universe. However, the mysteries hidden in the vastness of the Cosmos are countless, like the ones in the “dark sector”, which is formed by particles that cannot be easily observed, because they do not interact with our detectors; we only see their gravitational effects, as in the case of dark matter.

“Our project will look for particles different from the ones than one may expect to find in the LHC, as they would distinctively have a very little mass. Currently, there are independent efforts worldwide oriented to this search, but our goal is to propose new and better detection techniques,” Dr Arias explains. The research team in charge of this Fondecyt Regular project (1161150) “Looking for signatures of a hidden sector” is made up of scientists from Argentina, Germany, Spain and Switzerland.

According to professor Arias, their work is based on observational evidence in this field of study that suggests that the Universe has a higher content of particles if compared to what we see now. She explains that this information has led to the formulation of different theoretical models on the properties of these new particles and predictions about how we could watch them.

“Technological progress has been possible thanks to the knowledge and understanding of the world around us,” she adds. “Particle Physics is a basic science and its purpose is to understand the Universe where we live in. For now, we cannot measure how this will contribute to society. As we still have not learned about the intrinsic nature of these new particles, we do not know how they can be a contribution in the future. Undoubtedly, understanding the Universe is a question that has fascinated mankind since its origins.” 

For Dr Arias, being part of the Department Of Physics at Universidad de Santiago de Chile has been a great experience. "The level of the research work at the university is very high and we expect to continue strengthening it,” she concludes.

• Among the different speakers that took part in the Colloquium “Water: a renewable resource?”, one of them, Alfredo Zolezzi, founder of the Advanced Innovation Center, considers that the contrast between technology progress and the poverty and shortage of sanitary resources affecting millions of people is “dramatic”. He says that the solution to this problem is to make sure that innovation reaches people who need it.

The recent celebration of the World Water Day brought again to the national and international agenda the importance of promoting sustainable practices for the good use of water resources in the planet. The Colloquium “Water: a renewable resource?” was held in this context and it was led by the Association of Researchers for Development and Interdisciplinarity (INDI, its Spanish acronym), that groups researchers from the different faculties of Universidad de Santiago de Chile.

The activity brought together three speakers that approached the implications and significance of this strategic resource from very different points of view.

Leyla Noriega, journalist of Red Mi Voz*, who has experience in working with indigenous communities in the north of Chile, gave the presentation “Between the Andean world view and the community’s political core”. She explains that “our philosophy understands water like a living being. The resource is distributed according to its ancestral use by common law; that is to say, based on customs or natural rights.”

However, this expert in communications says that this approach is little respected, as a consequence of a series of processes that have affected the native peoples of the north of the country, like “Chileanization and the disassembly of ancestral authorities.”

Then, Alfredo Zolezzi, founder of the Advanced Innovation Center spoke about “Meaningful innovation”, considering it like a concept that has always been present in the history of humankind. “We have never had as much technology available as we do now, but it is dramatic to see this progress without recognizing that there are millions of people living in poverty, without basic sanitary services,” he says.

Effective solutions

In light of this situation that accounts for a complex reality, specific answers are required. According to Zolezzi, the solution lies in changing the way of doing things and he suggests “doing activism with proposals that make sure that innovation will reach people who need it.”
 
In his case, innovation became socially meaningful through the creation of the Plasma Water Sanitation System (PWSS), a water purification system that allows transforming polluted water particles into plasma, making it potable.

This system was implemented in 2011, in Fundo San José, a shanty town in Cerrillos, Santiago, thanks to a partnership with Un Techo Para Mi País**. It is worth to mention that this shanty town’s residents were resettled in June, 2013.

The last presentation was given by Dr. Silvio Montalvo, professor at the Department of Chemistry Engineering of our University, who spoke about his research regarding water resources.

At present, he is working on the treatment of sludge generated at sewage water treatment plants, in order to develop technologies to optimize the anaerobic digestion process that allows breaking down biodegradable material in the absence of oxygen.

“If we are able to preserve the water that we already have and keep it less polluted, we will be contributing to this matter,” the researcher says.
